Ed, what do you have running in the background? If anything like anti-stuff or anything that goes on the Internet to search for updates can cause this problem. If the nanosecond that background running program interrupts the CPU is at the same time the note is supposed to end then the DAW or BiaB will not get that message. Thus the note stays on. This is why I have my Ethernet card disabled even though my music computer is off-line 99.9% of the time.

You said that if you record a longer piece of music you get more stuck notes. Is it always the same note? Also this may indicated that something is not working properly in your keyboard. We had a similar problem when JonD's keyboard was dying.

My goal this weekend is to move just enough each day so that no one pokes me to see if I'm dead or not.
